Just like the other questions on this page, when answering this question, it’s best to be honest – especially because the answer you give to this one might end up influencing your role, should you get the job! So, you need to think carefully – and not rush into an answer!

With this one, if you can, try and name a few different elements and try to pick things which will make you stand out for all the right reasons. For example, you can design appropriately according the clients requirement, new ideas to make the design more effective and easy to read. You enjoy the design work by implementing new techniques.

It is the property of the material enabling it to be drawn into wire, with the application of tensile force. It must be both strong and plastic. It is usually measured in terms of percentage elongation and reduction in area, (e.g.) Ni, Al, and Cu.

Factors affecting endurance strength are

☛ Load ii. Surface finish
☛ Size
☛ Temperature
☛ Impact
☛ Reliability

A crack can propagate if the energy release rate of crack is greater than crack resistance.

The factors involved in arriving at factor of safety are:

☛ Material properties
☛ Nature of loads
☛ Presence of localized stresses
☛ Mode of failures

The factors effecting notch sensitivity are:

☛ Material
☛ Notch radius
☛ Size of component
☛ Type of loading
☛ Grain Structure

The bending moment equation is, M/I = f/y= E/R,

Where,

M – Bending moment (M is in N-mm)

I - Moment of inertia about centroidal axis (I is in mm⁴)

f – Bending Stress (f is in N/mm²)

y - Distance from neutral axis (y is in mm)

E - Young’s modulus (E is in N/mm²)

R - Radius of curvature (R is in mm)

☛ 1) Keep shop floor clean, free from oil and other slippery materials.
☛ 2) Wear proper dress and avoid loose clothing and loose hair.
☛ 3) Wear shoes and avoid chapels.
☛ 4) Avoid playing, loose talk and funning inside the shop floor.
☛ 5) Keep good housekeeping and put all unnecessary items and rejected items in scrap box.
☛ 6) Learn everything about the machine before starting and clear all the doubts.
☛ 7) Keep a safe distance from rotating and sliding parts.
☛ 8) Never store inflammable materials inside or around the shop.
☛ 9) Never play with electricity, fire, parts with sharp edge etc.
☛ 10) Keep fire buckets and extinguishers ready for use.

This is used to measure very small unit with greater accuracy. It consists of a primary scale and a vernier scale.Vernier scale slides on the primary scale.

Lettering is the presentation of information data on a drawing.
